The L200-40F High Limit Control Switch is a critical safety component designed for HVAC systems and forced-air heating applications. This fan disc thermostat functions as a thermal cutout, monitoring the internal temperature of the heat exchanger or blower housing to prevent overheating. When the temperature reaches its 200-degree Fahrenheit threshold, the switch automatically opens to break the electrical circuit, protecting the appliance from potential damage. Designed for reliability, this switch features a 40-degree differential, meaning it will automatically reset once the temperature cools to 160 degrees. It is an essential replacement part for ensuring the safe and efficient operation of commercial and residential furnaces and air handling units.
